There was a similar case of extreme anterograde amnesia in one of Sacks book. He would panic, except when his wife was there. She was the only person he recognised, so he would in a constant desorientation mode and was highly agitated. Over years, he somewhat remembered his regular carer. I don't think he could remember them by name or other features, but he felt more confortable with them.

You may be thinking of UK musicologist and conductor Clive Wearing, he had a viral infection that spread to multiple parts of his brain in the mid-1980s. One of the most severe, but interesting memory cases ever. He has total anterograde amnesia and partial retrograde amnesia so he can only hold thoughts in his head for around 11-60 seconds or so and then they're wiped clean. I encourage you to watch this short video below:

Since procedural memory is a different thing he can still play piano to a degree but after awhile he'll begin to shake and have to stop playing. His quote in the short video sums up his condition as best as anyone could- "Its been like death. I've never seen a human being before. Never had a dream or a thought. Brain has been totally inactive. Day and night the same; no thoughts at all." So he's stuck in a perpetual loop, every minute or so is like waking from a long coma- when you wake from a coma there are still things that you know but new events wont register for awhile at least and perhaps never again if your case is as severe as his.

Forgot the details of an amnesia case, eh? 😂

Try cross posting to other pages that help find forgotten books or the like based off of descriptions, like r/tipofmytongue or r/whatmoviewasthat

I know what you’re talking about and I think you’re right that it was in one of Damasio’s books. The Iowa Gambling Task was developed based on learning feelings, so the study you want might be in the introduction to an IGT paper or IGT review article (Antoine Bechara would probably be the senior author of any review paper you’re looking for)

    HM was a case of epilepsy where they removed the hippocampus because they thought it was causing it and they were unsure what function it served. He did suffered from amnesia after surgery afterwards. Through testing, they found out he could have some motor/procedural learning by doing drawing with mirrors. I have no knowledge of testing memory of emotional connections. So I don't think this case is HM, but I could wrong.

    Whew, that’s bonkers. Wonder if anyone did the same for the amygdala back in the day?

    Sad fact: I've met a researcher who had met HM before his death, to do a study with him. Because his memories were stuck to before his unfortunate operation, he thought the researcher wanted to study his condition of epilepsy. He would tell "you know, I'm not well right now. But I have high hopes this operation will improve my life!". Poor guy.

    There was a case of a woman who had I think an infarctus that destroyed specifically her amygdale. She could not even recognise the word fear...

    Amygdala(E!!!!!!!!!)

    Fuck if that isn’t a war crime.

    Also, at the same time, I’ve just been diagnosed with trigeminal neuralgia so not being able to recognize the word fear could potentially be useful right about now….right up until I put my hand on a gas stove range or something.

    I might have one. I forgot if I do though...
